Use perigee surface as target surface in fitting

Xiaocong Ai requested to merge use-perigee-surface-in-fitting into master

This MR includes the following changes:

  • Use perigee surface at beamline as target surface in fitting algorithm
  • Residual plot tools now plots residual/pull of fitted (perigee) parameter instead of parameters at each track state
  • Add plotting script for looking at perigee parameter resolution

An example of perigee parameter resolution with 10 GeV/c muon at Generic detector and ATLAS B field could be found here:perigee_resolution_pt10
